Question

You must use the full name, no abbreviations. Name the dynamic found around the cell. You will find this on the outside of a bacterium or a plant cell, but you will never find this n extracellular structure around an animal/mammal cell. The organelle is found in the cell, has a double membrane and is the location of DNA. This non-membrane organelle translates proteins. This membranous organelle has #4 associated with it. The membrane organelle receives material from #5 and modifies the lipids and the proteins. The digestive organelle of the cell is the The membrane organelle that produces ATP and other products is the: The network of proteins found through the cell, aiding in the placement and movement of the organelles is the: The specific proteins that comprise #9: The large "long" column of globular protein polymerized together: The microfilaments are composed of these 2 proteins. Name the membrane bound structure that moves material out of the cell. #8 is referred to as an endosymbiant. Why? Note the progression to form a protein.

Explanation / Answer

1. ANS: Cell membrane.

2. ANS: Cell wall.

3. ANS: Mitochondria (Circular DNA is present in this).

4. ANS: Ribosome's (The rRNA which present in the ribosomes can helps to translate mRNA into proteins).

5. ANS: Rough endoplasmic reticulum

6. ANS: Smooth endoplasmic reticulum

7. ANS: Lysosomes.

8. ANS: Mitochondria.

9. ANS: Cytoskeleton.

10- 12 ANS: G-Actin and F-Actin.

Each microfilament is formed with hundreds of globular subunits G-Actin organized into a double stranded helix with a 36 nm repeat F-Actin.

13. ANS: Exocytosis (In this plasma membrane surrounding substances inside the cell and moves it outside the cell).

14. ANS: Mitochondria is a endosymbiont

1. Mitochondria had its own DNA (Which is naked and circular).

2. Mitochondria have ribosomes that are mostly similar to prokaryotes.

3. Mitochondria is only produced by pre-existing Mitochondria.

4. Mitochondria can able to synthesizes their own proteins.

15-18. ANS:

Protein synthesis is a process in which cells build proteins from information in a DNA gene in a DNA gene in a two major steps.

A. Transcription: In which a molecule of DNA is copied into a complimentary strand of RNA.

B. Translation: In this the message in RNA is made into a protein.
